As shown in the figure, the short plug unit 10 apparently comprises a plurality of short plug units 10,
A pair of connecting bodies 11 having a shape, and an insulating body 12 for arranging the connecting bodies 11 at a predetermined interval from each other and insulating them.

If the mounting substrate 13 is flat, there is no problem. However, if the mounting substrate 13 warps before the surface mounting and the mounting surface has irregularities, it is necessary to deal with only the tail part of the connection body 11. Implementation may not be possible. Further, if the mounting board 13 warps after surface mounting, stress may be generated in the printed pattern of the mounting board 13 and soldering failure may occur.

能となっている。Means for Solving the Problems In order to achieve the above object, the present invention provides an electronic component for surface mounting in which a plurality of electronic component units are respectively surface-mounted on a mounting substrate. Are respectively composed of a connection body soldered to the surface of the mounting substrate and an insulating member holding the connection body,
The insulating members are connected to each other by connecting portions so that the surfaces of the respective connection bodies to be soldered to the surface of the mounting base are arranged in a straight line on the same plane, and furthermore,
The connecting portion is flexible enough to allow swinging of the electronic component unit in a direction perpendicular to the surface while the connecting body is soldered to the surface of the mounting base, and thus connected. The insulating member can be bent and separated at the connecting portion.

良が発生するおそれがない。[Operation] According to the present invention having such a configuration, even when the mounting surface of the mounting substrate (the surface to which the connection body is soldered) is warped before or after soldering, the connecting portion can be formed. Since the connector has flexibility, the electronic component unit follows the warpage (deformation) of the mounting base while the connecting body is soldered to the surface (mounting surface) of the mounting base, and the direction perpendicular to the mounting surface. Rocks. For this reason, even if warpage of the mounting base occurs, there is no possibility that defective soldering will occur.

装することが可能である。Note that the connecting portion only swings in a direction perpendicular to the mounting surface, and the positional relationship of each insulating member in the horizontal plane (the positional relationship of the mounting surface of the connecting body) is accurately held without change. Therefore, all the electronic component units can be simultaneously and accurately positioned on the mounting surface of the mounting base and mounted on the mounting board.

きる。In addition, the connecting portion where the plurality of electronic component units are linearly connected has flexibility and can swing as described above. However, in order to have such flexibility, the connecting portion is thin. According to the present invention, the electronic component unit can be freely separated by bending the insulating member at such a connection portion. For this reason, an electronic component for surface mounting consisting of an arbitrary number of electronic component units can be easily produced.

The bases 5 are connected to each other by a connecting portion 6, and the connecting portion 6 has flexibility. The insulator 3 and the base 5 constitute an insulating member according to the claims.

In addition, the short plug unit 1 can be separated by bending. When the short plug unit 1 is separated, it is necessary to apply a slightly larger force than when the flexibility is obtained without separating the short plug unit 1.

In this case, even if the mounting surface of the mounting board 13 is warped before or after soldering, the short plug unit 1 can follow up correspondingly. Further, since the connecting portion 6 can be separated by bending, it is possible to use only one short plug unit 1 as shown in FIGS. 3 and 4, or to connect a desired number of short plug units.
